I was receintly asking about some options for a top rated wood insert and one of the members of this site let me know that I have a zero clearance fireplace which seems to leave me w/ few choices. From the small size of my fireplace dimensions it looks like I will only be able to fit a wood insert w/ a small firebox. Here are my fireplace basic dimensions: fireplace opening - 42†wide, at rear of fireplace - 26†wide, fireplace opening - 23†high, fireplace depth - 17.5â€. I have a new construction house that is about 4 years old and is about 2300 square foot of interior space. Has anyone here put in a small zero clearance wood insert and had some success - saved some $ on heating in the winter? I have plenty of free wood and have all the tools I need to cut, split, haul, and store the wood but am hitting a serious road block w/ this Zero Clearance, pre-fab, and small fireplace of mine What options are out there? So far I have found the Jotul Winterport and one of the Pacific Energy small inserts seems to fit the bill. Is it worth it to spend upwards of $4000 - $5000 on a small insert to help heat my 2300sq ft. house?
